This pendant is set with a black opal from Lighnting Ridge, Australia, which has a green and some orange fire on a brown background. The triangular stone is fairly large, 1.7cm high and 1.5cm wide, and weighs 6.4 carat. I have set it in a simple, elegant and relatively chunky setting, which lets the stone speak for itself, yet adds aestetic appeal and complements the shape of the stone. The entire pendant is 3cm long and weighs 4.99 grams. The back of the hanger is hallmarked for Edinburgh 2016. The pendant comes with an 18″ Sterling silver snake chain and will be sent gift boxed.
